VICTORMadera Posted November 22, 2020 Share Posted November 22, 2020 Hi everyone, new mack owner here. I bought this 09 Mack and it runs really good but I have a problem... It shuts down exactly 15 minutes after. Runs really good except that issue with it shutting down every 15 minutes. No fault codes and starts right up again and runs 15 minutes and doesn't allow you to accelerate and shuts down as soon as you stop. It has the dpf deleted. Thank you in advanced.

mp8_macky Posted November 26, 2020 Share Posted November 26, 2020 one of my customers had exact same problem with mp10 few years back, issue was a bad delete. exact same thing, it would just shut down after 15min you have to use a trustful source of delete tunes 1 Quote Link to comment https://www.bigmacktrucks.com/topic/65026-09-mack-mp7-shuts-down-every-15-minutes/#findComment-464418 Share on other sites More sharing options...
VICTORMadera Posted November 26, 2020 Author Share Posted November 26, 2020 Do you have a recommendation to get it retuned. I am in Colorado.

todd Posted July 21, 2022 Share Posted July 21, 2022 I know this is an old post, but my truck is doing the exact same thing every 15 mins on the dot. Did you figure out the cause? thanks Quote Link to comment https://www.bigmacktrucks.com/topic/65026-09-mack-mp7-shuts-down-every-15-minutes/#findComment-503772 Share on other sites More sharing options...

mp8_macky Posted yesterday at 06:48 AM Share Posted yesterday at 06:48 AM in case of my customer, who had exact same issue, the solution was doing a full delete from scratch. it can be tricky to find someone who wants to work on a vehicle someone else worked on i have a very good relationship with https://truckecmtunes.com so they helped me out it is worth a shot to check their mack mp7 deletes, check their link https://truckecmtunes.com/mack-mp7-def-scr-egr-dpf-delete-tuning-kit.html Quote Link to comment https://www.bigmacktrucks.com/topic/65026-09-mack-mp7-shuts-down-every-15-minutes/#findComment-588473 Share on other sites More sharing options...
